PRINCIPLES OF OPERATION

NOTE:
- The smart junction box (SJB) is also known as the generic electronic module (GEM).
- The time out for the battery saver relay and the accessory delay relay is 1 minute if the vehicle has less than 80 km (50 miles). Both are controlled by the SJB. Once the vehicle passes the approximate mileage threshold of 80 km (50 miles), the time out for both relays will be the normal 10 minute time out, as described by the Owner's Literature.

The SJB communicates via the medium speed controller area network (MS-CAN).

The SJB controls the power door lock system. The module monitors the door lock/unlock switch inputs from the interior door lock switches. When the module receives an unlock/lock command from any door lock control switch, the module activates the door lock actuators. Refer to Locks.

The module also controls the following remote lock/unlock features:
- Remote keyless entry (RKE) transmitter lock/unlock (buttons are part of the integrated keyhead transmitter [IKT] key)
- Panic alarm (button is part of the IKT key)
- Keyless entry keypad

The SJB controls the autolamp subsystem. The autolamp subsystem provides light-sensitive automatic on/off control of the headlamps and parking lamps. Refer to Lighting and Horns.
